TREATMENT TABLE.

Application filed June 23, 1 919.

To all whom it may concern:

Be it known that I, F RANK KoENIG- KRAMER, a citizen of the UnitedStates residing at Cincinnati, in the county of .Hamilton and State ofOhio, have invented certain new and useful Improvements in TreatmentTables, of which the following is a specification.

My invention relates to improvements in osteopathic treatment tables.One of its ob jects is to provide an oscillatable and resilientlysupported table top section adapted to be applied to and used inconnection with a: table of ordinary construction. Another object is toprovide improved means to os cillatably and resiliently support anauxil- "iry table top section relative to a table of ordinaryconstruction. Another ,object is to provide improved self-containedmeans to 0 detachably support such an auxiliary table top sectionrelative to a table.- Another ob .ject is to provide self containedoscillatable and resilient supporting means and locking means therefor.My invention also comprises certain details of form, combination,

and arrangement, all of which will be fully set' forth in thedescription of the accompanying drawings, in which:

Fig. 1 is aside elevation of atable with my improvements attachedthereto.

Fig. 2 is a top plan of the same.

Fig. 7. is a sectional detail on line 77 of Fig. 1.

Fig. 8 is a sectional detail online 88 of Fig. 1. y The accompanyingdrawings illustrate the preferred embodiment of my invention, in which Arepresents a table of ordinary type or construction supporting a tabletop or top section 14 upon four legs 15 My improved apparatus comprisesa table top section 16 together with its'supporting and ad justingmechanism adapted to be either permanently or temporarily attached tothe main table A, for the support and treatment Serial No. 305,991.

of osteopathic patients the top section 16 The supporting and adjustingmeans for the top section 16 comprises a framework 17 to be attached toone end of the table A, preferably by bolting to the legs thereof at oneend. As illustrated the framework 17 consists of the angle bars 18extending horizontally from one table leg to the other and secured tothe table legs by screws or bolts 19, vertical bars 20 secured atopposite ends to the angle bars 18 to space them apart and formtherewith a rigid rectangular frame. Attached rigidly to the angle bars18 are journal bearings 21 and 22 in which bearings is journaled avertically disposed shaft or axle 24. Above the journal boX 21 is ablock or head25 rigidly attached to the shaft 24, and at the oppositeend of shaft 24 is a collar 26 rigidly attached to the shaft 24 belowthe bearing 22. The shaft 24 near its middle carries rigidly an eye-bolt27 one section of which, passes through a perforation in the shaft 24while other sections of the shank of the eye-bolt are encased in sleeves28 and 29, and the eye-bolts and sleeves rigidly locked to the shaft 24by means of a nut SOthreaded to the end of said eye-bolt. Eye-bolts 31and 32 arerigid/ ly attached to the vertical bars 20 respectively, andsprings 33 and 34 are each connected at one end to the eye of the bolt27 and at their opposite ends are respectively connected to theeye-bolts 31 and 32 so as to put a yielding tension on the shaft 24tending to normally hold said shaft in a predetermined position ofequilibrium. A hand lever 36 is pivotally attached to one of thevertical bars 20 so as to be movable with considerable frictionaltension relative to the frame 17 Said hand lever carries rigidly abracket'or projection 37 having a recess 39 in position to engage thesleeve 28 when the hand lever 36 is depressed, and thereby to lock theshaft 24 against rotation in its bearings 21 and 22. A pivotallyconnected brace member 40 serves byengaging its lower end 41 with theeye-bolt .31 to hold the hand lever 36 in an elevated position, and thebracket 37 out of engagement with the sleeve 28, in which position theshaft 24 is rotatable under the tension of the springs 33 and 34.

Attached to the under side of the top section 16 are bracket arms 43 and44 which are pivotally attached to the head 25 on the axle 24, therebypivotally connecting the top section 16 to the shaft 24 so as to bemovable relative to said shaft 24 in a vertical plane, and also movablewith said shaft 24 in its hearing 21 and 22, Parallel arms 45 and 46 arepivotally connected at one end to the collar 26 so as to move with saidshaft 24 in its journal bearings. At their free ends the arms 45 and 46are connected together by means of a bolt 47 which also serves as ajournal for the forked. tubular member 48 and also as a. journal bearingfor the journal box 49, as illustrated in Fig. 8. An eyebolt 50 ispivotally attached at one end to brackets 51 which are rigidly attachedto the under side of the top section 16. A. nut 52 is threaded to theshank of the eye bolt 51, which nutseats upon the upper end of thesleeve or tubular portion of the member 48, while the lower end of theshank of the eye bolt 51 rests and is free to slide loosely in the bore53 of the member'48. The members 48 and 51 are held yieldingly inengagement by means of a spring 54, which at its upper end is connectedto. an eye 55 carried by the bearing 21, and at its lower end to a slideor carriage 56 guided by and between the parallel arms 45 and 46. Thetension of the spring 54 holds the nut 52 yieldingly in engagement withthe endof member 48, and adjustment of the nut one way or the othertends to increase or decrease the distance between the eye of bolt 51and the bolt 4", thereby tending to adjust the top section 16 topositions of inclination either above or below the horizontal positionshown in Fig. 1. The tension of the spring 54 is also transmittedthrough the slide 56, the arms 45 and 46, the bolt 4'7, member 48, andevebolt 51 to yielding or resiliently support the top section 16 in anypredetermined position with reference to the shaft 24 and its pivotalconnection to the head 25 thereof. Movement of the slide or carriage 56along the arms 45 and 46 tends to materially increase or decrease thetension or lifting effect of the spring 54, depending upon the directionin which the slide 56 is moved, thus providing for adjusting the tensionof the support for top section 16 to correspond with the weight of thepatient being treated. The carriage 56 is adjustable along the bars 45and 46 and locked to any adjusted position by means of a screw shaft 58threaded to the slide 56 and journaled in the journal box 49, in whichit is held against movement endwise by the collar 59 at one end and bythe hub of the crank arm 60 at the opposite end,

A tubular member 61 is, pivotally connected to one of the arms 45 and 46and is slotted at its free end and provided with a clamping screw 62.The member 61 is telescopically engaged by a bar or rod 64 which ispivotally connected at 65 to the top section 16. when it is desired tolock the top section 16 against oscillation vertically the tubularmember 61 and rod 64 are clamped together by the screw 62, which limitsbut does not entirely prevent movement of the top section 16 vertically,since heavy pressure downwardly on the top section 16 will result inelongating the spring 54 and sepa rating the nut 52 to a greater or lessdis tance from the end of tubular member 48.-

At any time the top section 16 together with its supporting andadjusting mechanism, which is of relatively light weight compared withthe table A, may be dctached from the table A and moved to anotherlocation and attached to another table of the same general type as tableA. which is of importance in thinly settled localities, and where itwould be diflicult to transport a complete or heavy table.

The apparatus herein illustrated and de scribed is capable ofconsiderable modification without departing from the principle of myinvention.

1. A table attachment comprising a rigid frame separately attached totwo adjacent legs of a table near the upper extremities of said tablelegs and near the lower extremities of said table legs and serving tothereby add to the rigidity of the table and at the same time afford amore firm and rigid support for an oscillatable table top section, avertically disposed shaft journaled to said frame, a table top sectionpivotally attached to the upper end of said shaft and oscillatablevertically with reference to said shaft and horizontally with said shaftin its bearings, means carried by said frame to resiliently support saidtable top section vertically, means attached to said frame and to saidshaft to yieldingly support said shaft in a predetermined position withreference to said frame, and means to positively lock said shaft againstrotation relative to said frame.
